9. TROUBLE SHOOTING

Do not perform any maintenance with engine on. Below are listed a few small difficulties which
may occur and which can be solved by the user.
1) Gasoline engine does not start. Make the following checks in the order given:
• The fuel tank is at least half full;
• The fuel tap is open;
• A cold motor must be chocked;
• Fuel reaches the carburetor;
• The breather hole in the fuel tank cap is not clogged;
• The carburetor filter is clean;
• Carburetor jets are clean. Screw them out to inspect them and, if dirty, clean them with a
blast of air;
• The sparking plug sparks. Take out the plug, reconnect it to its wire, touch the plug metal part
to the metal part of the machine, and turn the pulley as to state the motor. If a spark is not
seen between the plug electrodes, see if the plug wire connections are tight. If currents still
does not reach the electrodes, change the plug.
If the motor still does not start with a new sparking plug, the trouble is to be found in the
electrical system, points, condenser, coil or other parts. It is advisable to turn to the nearest
service point or specialized shop.
2) Diesel motor does not start. Make the following checks in the order given:
• The breather hole in the fuel tank is not clogged;
• The fuel tank is at least half full. If surrounding temperature is very low, fill the tank, located
on the head and closed with a rubber plug, with motor oil.
• If the motor still does not start, purge the fuel lines of air according to the instructions given
by the motor manual. If the motor still does not start, go to the nearest service center or a
specialized shop.
3) The gears do not engage:
• Adjust the clutch, unscrewing adjusting screw B (fig.17) on he down clutch handle C,or
adjusting screw D (fig.38) on he above clutch handle B, until the clutch disengages properly.
4) Two-wheel tractor with rotary hoe; the machine jumps forward on hard ground:
• Adjust the central knife moving it to the last hole as shown the related manual.
5) Machine with the cutter bar; the blade coupling breaks frequently:
• Make sure blade-holders are not too tight;
• See if there are stones on the ground; if so, lower the cutting height adjustment slides to
prevent small stones from wedging between the teeth and the blade.
6) Cut grass falls in front instead of being ejected at the sides (sickle cutter bar):
• Adjust conveyors position or remove shoes. When ope-rating in this way, the cut grass will
have to be separated from uncut one by hand to prevent clogging. The "Europa" bar is very
useful in these conditions to avoid this kind of problem. See related manual.
